Catfish Tesla’s every move always attracts the attention of the public. As a staunch supporter of renewable energy, Musk has spared no effort to promote electric vehicles to the public. But long before Tesla was born, there were electric cars in the automotive industry. In the 1920s, in economically developed cities such as New York in the United States, London in the United Kingdom, and Paris in France, more electric vehicles were driven on the streets than fuel vehicles. At that time, these vehicles used lead-acid batteries. But it was not until the advent of the internal combustion engine reversed the competition between fuel vehicles and electric vehicles, and the assembly line invented by Henry Ford made mass production possible. When one assembly line can produce 1 million cars, a car that originally cost $4,700 will drop to $380. Even ordinary blue-collar workers can afford a car. In 10 years, almost all electric cars on the street disappeared. History is always surprisingly similar. 100 years later, what happened to fuel vehicles is re-interpreted in electric vehicles, but the footnotes have undergone earth-shaking changes. Lithium-ion batteries, autonomous driving, on-board sensors, OTA…a series of new technologies are changing the definition of cars, and Tesla is undoubtedly the initiator and leader of this change. The Tesla model scares traditional car companies. The CEO of Volkswagen Group, the traditional car company, has publicly admitted that Tesla is leading the way in the field of autonomous driving software. Volkswagen needs to catch up. After all, no one wants to be the next Nokia. To this end, the world’s largest traditional car company has established a “Digital Car&Service” department, determined to become a software-driven company to meet the challenges of software-defined cars. And without the burden of fuel vehicles, Tesla has been in the electric vehicle industry since its inception in 2003, constantly pursuing mass production and reducing prices, and has developed a business model that is different from traditional car companies. With these two, Tesla can let more people buy cars, and the more users can buy cars, Tesla can use a large amount of user data to help optimize and iterate back-end autonomous driving algorithms and software Service, thus forming a positive feedback. Tesla is relying on sales, price, and technology to form a solid “iron triangle” to help Tesla, which is taking the route of pure visual algorithms, build a high wall that latecomers cannot overcome. 01 Price reduction is king Tesla loves to cut prices, it is obvious to all. The domestically produced M3 has been priced at 355,800 yuan since its release in May 2019, and has dropped 5 times in less than two years. Currently, on Tesla’s official website, the price of the lithium iron phosphate version of M3 + standard battery life + subsidies is 249,900 yuan, a decrease. Nearly 1/3 of the original. Another model, Model Y, also cut prices. At the beginning of the year, Tesla announced that the price of MY is about 150,000 lower than the imported version. Recently, it has been reported that Tesla will launch the Model Y equipped with lithium iron phosphate in July this year, and the price of Model Y is likely to fall further by then. Explore. Frequent price cuts have also made Tesla a frequent visitor to the headlines. The latter likes to call Tesla’s price cuts again and again as “cutting leeks.” But the actual situation is far from the conjecture of these media. Because since the day Musk took over Tesla, mass production and price reductions have been carved into Tesla’s bones. For the time being, back to 2006, Tesla, which has just completed its Series A financing, launched its first electric car, the Roadster, at the Santa Clara Auto Show in California. This is a niche and expensive two-seater roadster. At that time, Tesla’s weak financial resources made the company’s efforts to create two Roadster concept cars, one red and one black. As the only electric supercar in the audience, Roadster also lived up to expectations. , Attracted the attention of a large number of media and celebrities. At the press conference, Tesla announced that each Roadster car is priced at $90,000, and it can last 250 miles on a single charge. On the same day, 30 people promised to buy Roadster cars on the spot, including Google co-founders Brin and Pei. Odd, there are many billionaires in the field of science and technology. But man-made electric cars for the rich are only the first step of Tesla’s ambitions. Musk really wants to popularize clean energy and build an electric car that the public can afford. Only one month after the auto show, Musk proposed Tesla’s development roadmap “Master Plan”: 1. Build a sports car (Roadster); 2. Use the money earned to build a cheaper car (Model S/X); 3. Use the money earned to build a cheaper and best-selling model (Model 3); 4. While achieving the above, it also provides zero-emission power generation options. Automobiles are a typical technology and capital intensive industry, and countless start-ups have become cannon fodder. The fledgling Tesla is difficult to compare with traditional car companies in terms of manufacturing technology, supply chain management, and corporate branding. In addition, at that time, the entire electric vehicle industry chain was immature, the industrial supporting facilities were not perfect, and the battery cost was also high (10 times the current price). To be a popular and cheaper electric vehicle, both economically and practically It is very difficult to land in terms of operability. That being the case, it’s better to launch high-end electric sports cars for high-income groups from the very beginning, subverting people’s perception of electric vehicles with short cruising range and poor performance; when the time is right, they can reduce costs, mass produce, and promote cleanliness. Energy and other strategies. But even so, Roadster still encountered mass production problems, and the production cost exceeded the expectations of the Tesla team. Due to the lack of economies of scale in supply chain procurement, Roadster’s production costs have risen from an estimated US$65,000 to more than US$100,000, while Roadster’s price is only 90,000. In other words, every time a car is sold, Tesla will have to reverse the price. Ten thousand U.S. dollars. The heavy cost pressure put Tesla on the verge of a desperate cash flow break. The leaks happened in the night. In 2008, the global financial crisis broke out. Another Musk company, Space X, also failed to launch rockets one after another, unable to support Tesla. This electric car upstart unknowingly came to the brink of bankruptcy. Unexpectedly, the helping hand came from Tesla’s rival, the German auto giant-Daimler Group. In 2009, Musk received 50 million dollars from Daimler to renew his blood. At that time, Daimler Group was looking for a power battery provider for its Smart electric version. Musk heard that he directly bought a Smart and converted it into an electric version, and invited Daimler engineers to test drive. The electric car was amazed. After the contract was concluded, another US$50 million was invested in exchange for a 10% stake in Tesla. But this amount of money is really a drop in the bucket for Tesla, a “black hole”. At that time, Tesla’s annual revenue was only US$147.6 million, but business expenses were nearly 400 million, and a net loss of US$260 million. In addition, Tesla also needed a lot of funds to support the development and production of the second car Model S. The fire-fighting water still comes from the US federal government. After Tesla won the Daimler order and showed off the Model S concept car, the US federal government gave Tesla a low-interest loan of 465 million to encourage research and development of alternatives. Energy vehicles. In addition, Tesla also raised 226 million US dollars through the listing. After slowing down, Tesla won an order for an electric version of the RAV4 battery from Toyota, and at a low price of 42 million US dollars from Toyota CEO Akio Toyoda, Toyota and General Motors jointly built a car processing plant (now Fremont factory). It is reported that this factory is not only close to Tesla’s headquarters at that time, but also has an annual production capacity of 500,000 vehicles, laying a solid foundation for Tesla to control the cost of car production. The mass production and delivery of the second model Model S is on schedule. Compared with the first Roadster, the price of this four-door coupe is only 57,400 US dollars (standard endurance version), which is 63.7% of the Roadster, but it is not inferior in hardware performance, with the fastest acceleration of 4.4 per hundred kilometers. Seconds, the cruising range can reach up to 483 kilometers. More importantly, Model S creatively introduces a 17-inch central control touch screen, which integrates the entire vehicle’s information query, navigation, music, game and other functions on a single panel, which is like installing an iPAD for this type of car. , Users can enjoy the OTA over-the-air upgrade service of in-vehicle software on a regular basis just like enjoying the upgrade of a mobile phone upgrade system. This can ensure that each car owner can enjoy the latest software services, such as the Autopilot automatic driving assistance function launched by Tesla in 2014. Not surprisingly, ModelS sales far exceeded expectations, becoming Tesla’s first mass-produced car in the true sense. At the end of 2012, the pre-ordered Model S had reached 15,000; in 2013, Tesla delivered a total of 22,477 Model S. Compared with 2,500 Roadsters, Tesla’s mass production delivery capacity has increased by nearly 10 times. Relying on the great success of Model S, Tesla turned a profit in 2013Q1, but Model S is still a sports car, and the price is still high. The competitors it dropped are old luxury cars such as Mercedes-Benz S-series and BMW 7-series. The Model X that was launched in 2015 was not enough for civilians, and the price was around $50,000, so Musk also needed more affordable electric vehicles. It was not until March 2016 that Tesla launched the Model3, and Tesla ushered in a truly explosive model. Model3 Standard Edition starts at USD 35,000 and has a range of 354 kilometers, which is extremely cost-effective. Since its delivery at the end of 2017, Model 3 has continued to surpass traditional luxury fuel vehicle brands such as BMW, Mercedes-Benz, and Audi. At the same time, it has taken the first place in the market among similar new energy vehicle brands. According to statistics from EV Sales, from January to September 2020 The monthly global cumulative sales of new energy passenger vehicles was 1.784 million, of which Model 3 is the world’s best-selling model, with cumulative sales of 238,000, accounting for 13.4% of the world’s total. So far, the three-step strategy “MASTER PLAN” proposed by Musk in 2006 has basically been realized, but it is not enough. Comparing the prices of Tesla Model 3 and Model Y before subsidies and the selling prices of other top ten models in the US auto market, the price of Tesla cars is still 17%~31% higher. In other words, Tesla is still one step away from the price that the public can afford to buy a car. In February of this year, it was reported that Tesla would launch a Model series car with a price of 25,000 US dollars (160,000 RMB), which undoubtedly aimed directly at the current best-selling models on the market. On Tesla Battery Day 2020, Musk once said that starting with the heart battery of electric vehicles, he will reduce costs and increase efficiency in cell design, battery production, cathode materials, anode materials, PACK, etc., so as to reduce the cost per KWh. 56%, which in turn provides profit margins for price cuts. The Huachuang team calculated that after the price of Tesla Model 3 was cut by 23,900 yuan in October last year, it would need a sales increase of 20%-27% to obtain the previous total profit. Some investors also asked Musk at Tesla’s 2020Q3 investor conference, when the result of the price cut is that the company cannot achieve its profit margin target, will the company still cut prices? Musk said, “We hope that Tesla’s cars will be affordable to users, and we have to separate the concepts of affordability and cost-effectiveness. If the car is too expensive, consumers cannot afford it, regardless of It doesn’t matter what value proposition you have, so it’s important to be able to afford it…” It is not difficult to see that Musk is more concerned about the sales performance of the car than the price. And each price cut really stimulated Tesla’s sales. According to data from the Federation of Passenger Transport Associations, the domestically-made Model 3 lowered its price to 249,900 yuan from October last year, and its sales in October, November and December reached record highs, reaching 12,000, 22,000 and 24,000 respectively The domestic Model 3 2020 annual sales volume reached 135,000, in other words, Q4 single-season sales accounted for 42.96%. The same is true for Tesla’s full-year sales performance in 2020. Q4 sales exceeded 180,000 in a single quarter, accounting for 36% of the annual delivery of 499,647 vehicles. The side effects of the price cut are also obvious. The gross profit margin of Tesla’s automotive business in Q4 was only 24.1%, a decrease of 3.6 percentage points from the previous quarter, which was the lowest level in the year. The net profit attributable to the parent was US$270 million, which was in line with market expectations of 7.63. Billion dollars, far away. After the Q4 financial report was announced, Tesla’s stock price fell in response, and its market value shrank by nearly 60 billion U.S. dollars in one day. Since then, it has continued to fall. It has fallen to a March low of 539 U.S. dollars per share before stabilizing, and a total of 346 billion has evaporated. The trillion-dollar market value that once approached Apple has also become a bubble. Just when the public believed that Tesla was returning to a reasonable valuation range, many people believed that Tesla was undervalued. They said that Tesla will surpass Apple in the future to become the world’s largest company. The reason behind this is that Tesla is far from An ordinary car manufacturer, but a technology company with Saas service attributes. 02 The Meaning of Drunkard Selling a car is the face, and the software is the lining. For a long time, the automobile industry has relied on the manufacture and sales of new cars for profit, and automobile selling points have been focusing on the three major aspects of performance, appearance and brand. However, under the wave of electrification and intelligence, as a new dimension, in-vehicle software has become a new aspect of user purchase and profitability of auto companies. In other words, sales are transformed from purpose into means, and eventually flow to payment for in-vehicle software. When Tesla was the first company to run through this business model, the market’s perspective on this type of emerging car company changed. It was no longer the valuation of traditional automakers, but with SaaS service attributes. Valuation model for technology companies. Although the Tesla Model series will continue to reduce prices in 2020, Musk has also frequently increased the price of the on-board software FSD. Its Auto-Assisted Driving Software Package (FSD) has entered the price increase channel since January 2019, and has been gradually increased from the original US$6,000 to US$10,000 (or 64,000 yuan), which is equivalent to 1% of the price of the standard battery life version of the Model. /3, and the price increase momentum remains unabated. In order to inspire more car owners to use FSD, Musk changed the original one-time payment model and introduced a monthly subscription fee model ($100 per month). In the FSD that Tesla provides to car owners to purchase, it includes functions such as automatic assisted navigation driving, autonomous assisted lane change, autonomous parking, and smart calling. Among them, automatic driving technology is the top priority. In the “Key Points for Standardization of Intelligent Connected Vehicles in 2020” issued by the Ministry of Industry and Information Technology, autonomous driving technology is listed as a key element of the standard formulation and evaluation mechanism for intelligent connected vehicles. The research and development of autonomous driving is a typical artificial intelligence research and development engineering system, which is mainly based on three elements: algorithm, computing power and data. The algorithm solves the problem from zero to one, and the organization and optimization goals of the subsequent overall data engineering system. , Computing power is the physical basis for the realization of the model, and better algorithm efficiency and energy consumption indicators can be obtained through self-developed acceleration chips. But for autonomous driving, data is the core. Robin Li once proposed that the AI ​​era needs to switch to a new “AI thinking”. AI is different from the core of traditional software R&D system in that the implementation of traditional code functions is handed over to data and algorithms. Among them, the algorithm gap is easier to make up through open source and talent mergers and acquisitions, and data is the core barrier to differentiation. “Data spike algorithm “It is becoming the consensus of the industry. As the first electric vehicle brand to be equipped with an automated assisted driving system, Tesla also has the world’s largest assisted driving fleet, and has a huge first-mover advantage in terms of driving data. Beginning in 2019, sales of Tesla models have surged, and Tesla Autopilot’s mileage has ushered in explosive growth, from 1.73 billion kilometers in January 2019 to 4.828 billion kilometers in April 2020, doubling in a year, far exceeding Other competitors. The huge amount of real data makes Tesla’s data accumulation in high-precision maps and obstacle recognition significantly ahead of its competitors, and it is also more conducive to iterative algorithm updates. In contrast, other autonomous driving companies have been left behind. Behind. Musk himself announced on Twitter that the latest version of FSD Beta V9.0 has completed a new round of iteration. This time, the millimeter wave radar will be removed and become a complete pure vision solution, which is expected to be realized only by vision algorithms. Autonomous driving at L5 level. However, the new plan did not get the market’s appreciation. Instead, it attracted many doubts, believing that Tesla was too aggressive. Due to the low accuracy of camera sensors, there are some inherent shortcomings, such as poor night effects and susceptibility to extreme weather. Many experts believe that to achieve L4/L5 level of automatic driving, higher-end vehicle sensors such as lidar are needed. to realise. Lidar has high accuracy and detection range of up to 0-200m, which can greatly reduce the difficulty of software and hardware analysis, and can accurately predict objects at night. The day after Tesla’s official announcement of the withdrawal of the radar news, the National Highway Traffic Safety Administration (NHTSA) revised the Model 3 and Model active safety feature labels; after that, the authoritative third-party review magazine “Consumer Reports” It also announced the suspension of listing the 2021 Model 3 as a “recommended”. As public opinion continues to ferment, Musk has to explain to the public through the EV vertical media Electrek that even if there is no radar, the camera can achieve the work done by the radar to ensure the safety of autonomous driving. NHTSA is currently retesting the new model (without radar). In fact, Tesla is not the only company that takes the purely visual route for autonomous driving. The top players in the autonomous driving field, Mobileye and Baidu Apollo, both have products that are positioned on the purely visual route, SuperVision and Apollo Lite. Mobileye is an Israeli company. Tesla’s first-generation autopilot solution was handed over to Mobileye. However, after the death of autopilot in 2016, Tesla and Mobileye parted ways. But looking at the field of autonomous driving, Mobileye is a recognized top supplier in the industry. Its EyeQ series of chips have been adopted by 27 automakers, many of which include traditional car giants such as General Motors, Volkswagen, and BMW, as well as other car manufacturers such as Weilai and Ideal. New forces. Just last September, Mobileye 360° pure vision sensor solution SuperVision debuted at the Beijing Auto Show for the first time, serving the Geely Group’s high-end car brand-Lynk & Co Electric Vehicle Zero. It is reported that the solution is equipped with two EyeQ5 chips with a 7nm process and a computing power of 24TOPS. It is equipped with seven long-range cameras and four parking cameras. There are no sensors such as lidar and millimeter wave radar. Baidu, which has been using lidar, also launched its own pure-vision autonomous driving solution Apollo Lite at CVPR in 2019. From the multi-sensor solution to pure vision, the sudden change of Baidu made the public feel puzzled. At the meeting, Wang Liang, chief of Baidu’s Autopilot Committee, said: “Many sensor fusion scheme designs are more complicated, and technicians often design algorithms from the perspective of quickly solving problems. In this process, it is inevitable to use the respective advantages of heterogeneous data to complement each other to avoid difficult problems.” “Although the multi-sensor fusion scheme designed based on this idea can circumvent the problems that the single-sensor scheme is difficult to solve in the short term, in the long run, the design of deep coupling between data and strategy is not conducive to providing real redundancy for the environmental perception system.” “In the traditional strategy of lidar-based and vision-assisted, the problems and deficiencies of visual perception itself are not sufficiently exposed under the cover of radar perception. Therefore, the problem of visual perception needs to be independent to be better solved.” At the same time, Wang Liang also expressed his views on the camera: The camera is a relatively mature sensor. In addition to the advantages of light weight, low cost and compliance with vehicle regulations, the development trend of imaging technology with high resolution and high frame rate (imaging frequency) means that the image contains more environmental information, and the video data is also It is most similar to the real world perceived by the human eye, but compared with three-dimensional point cloud data, the information in two-dimensional images is more difficult to mine, requiring the design of more powerful algorithms, the accumulation of large amounts of data, and longer-term R&D investment. A brief summary of the above is that there are potential risks in taking the multi-sensor fusion route. The pure visual route can make up for this defect, but the pure visual route requires a large amount of data accumulation and long-term research and development to train the background algorithm, and data acquisition and algorithm deduction are extremely barriers. It is difficult for most car companies to adopt in the short term. It can be seen that the pure visual route is the kind of difficult but correct thing that everyone often says. At present, Mobileye and Apollo have both pure vision solutions and multi-sensor solutions such as lidar. Tesla has chosen a way to go to the dark. One example is the removal of millimeter wave radar. The “courage” behind Tesla is From: self-developed chip FSD, self-supervised learning neural network algorithm, supercomputer Dojo. Someone once helped Tesla calculate an account. At present, there are more than 820,000 Teslas equipped with HW 2/3 hardware driving around the world. The average user drives about an hour per day (8 cameras per car). ), the fleet generates approximately 196.8 million hours of video every month. The huge amount of data puts high demands on the computing power of autonomous driving chips. Before self-developed FSD, Tesla had used the Mobileye EyeQ3 chip and the NVIDIA Drive PX2 chip, but their computing power could not meet Tesla’s needs. Therefore, in 2015, Musk personally found Jim Keller, the chip god who just resigned from AMD, and asked him to develop Tesla’s self-driving chip. The importance of self-developed chips is to achieve deep adaptation of software and hardware to achieve minimum energy consumption and optimal performance. Among smart phone brands, Apple, Huawei, and Samsung all do this. The biggest feature of FSD’s self-developed chips is that they “only serve one customer-Tesla”, while chip companies such as Mobileye and Nvidia have many downstream customers and have to make a general chip solution. At present, the computing power of the FSD platform is 144TOPS, the computing power of a single NPU reaches 72TOPS, the preparation process is 14nm, and it is equipped with HW3.0. But just in Q4 of 2020, TSMC said it will take Tesla’s 7nm order and use the latest InFO_SoW packaging technology. At that time, the computing power of FSD is expected to increase by 4 times, and the probability of increasing to more than 500 TOPS is very high. In addition to the chip, Tesla trains a set of neural network algorithms that can be self-supervised learning. As of April 2020, Tesla’s true road test mileage has accumulated to 4.8 billion miles. If these data are all manually labeled for algorithm iteration, it will undoubtedly be a huge expense. To this end, Tesla’s senior AI director Andrej Karpathy launched the “Operation Holiday” data automation plan. Tesla’s deep neural network will directly mine the characteristics of the data itself, instead of manually labeling the data set, so as to carry out the perception algorithm. Continuous iteration, the ultimate goal is to complete full automation, without human intervention throughout the process. Just when everyone was wondering why Tesla supports huge data for deep learning, the cloud training supercomputer Dojo behind it also surfaced. Generally speaking, supercomputers are national-level special equipment, providing super-fast computing speed and super-large storage capacity for the high-tech fields and cutting-edge technology research needs of various countries. Among the top 10 supercomputers in the world in 2020, Japan’s Fujitsu topped the list with a peak performance of 0.415 exaflops; the second place in the United States was Summit with a peak performance of 0.148 exaflops; China’s Shenwei Taihu Light ranked first Fourth, the performance is 0.093015 exaflops. How does Tesla Supercomputing Dojo perform? Musk once said that the peak performance of the Dojo supercomputer should reach the level of exaFLOP per second, which is a trillion floating point operations. (Original words: A truly useful exaflop at de facto FP32.) At that time, Dojo will surpass Fujitsu of Japan and become the world’s number one supercomputer. These bold remarks aroused countless speculations by the public, and at the 2021 Computer Vision and Pattern Recognition Conference on Monday, Karpathy disclosed some of the operation of Tesla’s latest version of Supercomputing, which will serve as the development prototype of Dojo. . It is reported that the current Tesla supercomputing operating speed is 1.6Tbps per second, and the peak speed per second is 1.8Eflops. Karpathy said: “If you count FLOPS, this supercomputing can rank fifth in the global supercomputing rankings. This position is currently occupied by Nvidia Supercomputing Selene. This cluster has a similar architecture to Dojo and a similar number of GPUs (4480 vs. 5760 for Dojo).” This supercomputer has helped Tesla process more than 1 million videos of about 10 seconds, and marked the distance, acceleration and speed information of 6 billion objects in the video. The data storage space has reached 1.5PB. This new version of supercomputing is not the ultimate version of Dojo. Tesla’s supercomputing is still iterating and evolving. Musk’s goal of computing power to reach 1exaflops of Dojo is expected to be unveiled on Tesla AI Day at the end of July this year. . 03 The future is here Tesla’s various layouts for autonomous driving have long gone beyond the scope of traditional car business, and subverted the latter’s perception of cars. In 2018, the American authority “Consumer Report” pointed out that Tesla Model 3 has the problem of too long braking distance, so it did not recommend it. Tesla engineers upgraded the system through OTA (Over-the-Air Technology), shortening the braking distance by 6 meters, and solved the problem in just a few days. It is almost unimaginable that the replacement takes place in traditional car companies, because the solution of traditional car companies is most likely to be through large-scale recalls, or replacement of parts through 4S stores, which requires car owners to wait a long time. OTA is not a new thing. It refers to remote application management of mobile terminal devices through the network. Most people can experience it on their smartphones, such as mobile phone system upgrades and application software updates. Analogous to mobile phones, car OTA can also be divided into two categories: FOTA (Firmware OTA) firmware update and SOTA (Software OTA) software update. Most traditional car companies can implement SOTA, which can remotely update car map display, audio, video and other infotainment systems, but like Tesla, it can’t do anything to update the brake system. The latter involves rewriting the firmware program to realize the car. Renewal of power system and chassis system. Behind this can and can’t, reflect the deeper reasons, the difference between the electrical and electronic architecture (Electrical/Electronic Architecture) at the bottom of the two. Cars have many functions, ranging from the control of lighting, wipers, and windows to the ABS (brake) system, assisted driving system, map display, audio-visual player, etc., all handed over to Electronic Control Units (ECUs) to realise. The electrical and electronic architecture is the layout of these ECUs, which can be roughly divided into three categories: distributed, domain centralized, and centralized. Under the traditional distributed EEA architecture, each ECU has a corresponding relationship with the realized function. The hardware and software functions are deeply coupled. When the car has more functions, it also means the number of ECUs and wiring harnesses, which greatly increase the weight and cost of the car body. . These ECUs come from different suppliers and have different embedded software and underlying codes. The computing power cannot be coordinated, and the OEM has no right to maintain and update the ECU. In addition, different ECUs may have overlapping functions, leading to mutual redundancy and increasing unnecessary costs. In this context, traditional cars want to update their technology or firmware and rely more on the iterative completion of the model. That is to say, consumers need to keep changing new cars to enjoy the latest technical services, especially when it comes to chassis and power system updates. Distributed architecture is undoubtedly a big shackle for the intelligent upgrade of automobiles. In this regard, for the first time, Tesla adopted a centralized electronic and electrical architecture, using the central processing unit to uniformly manage different domain processors and ECUs, decoupling hardware and software, and opening up all hardware resources, including firmware and Complete vehicle OTA including software. Under the framework of centralized electronic appliances, automobiles are moving towards wheeled computers. Su Jing, head of Huawei’s autonomous driving product line, once said: “Traditional automakers think that the base of a car is a car, and try to embed a computer on the basis of the car. We think that the basis of the car is a computer, and the car is a computer-controlled exterior. Assume.” As early as June 2012, Tesla carried out an OTA upgrade to the first production car Model S. In 2017, Tesla implemented a centralized EEA architecture for the first time in Model 3 models. Since then, Tesla has carried out more than 120 OTA updates, including software OTA for autonomous driving, entertainment applications, and batteries. Firmware OTA for management and improvement of brake horsepower. In 2019, the foreign automotive media Top Gear released a performance test comparison video between Porsche’s Taycan Turbo S and Tesla Model S Performance in the tubing. The Taycan Turbo S accelerated at 402m, 0-96km/h, and 0-161km/h. Win the test. Some netizens questioned the rationality of the test, saying that the model tested by Top Gear is not Tesla’s latest Model S, but an old model from 2017, and the newly released 2019 new model has a significantly improved drive system and endurance. . Musk replied to the comment, agreeing, and let Tesla engineers optimize the motor control of Model S, and increase the peak output power of Model S by 50 horsepower through OTA. The upgraded Model S will be able to ensure that it is 402m. , 0-96km/h, 0-161km/h acceleration test, beat the Porsche Taycan with a greater advantage. Smart cars represented by Tesla are reshaping the definition of “cars” in the automotive industry. In the past, the completion of the delivery of a new car has meant the beginning of depreciation. The biggest change that Tesla has brought is to continuously improve the performance of the car through frequent use of data collected from the OTA (Over the Air) interface. In the process of using the car, a large amount of data and demand will be generated, which will be fed back to the car companies. On this basis, the car companies will continue to optimize and iterate their products, and then synchronize them to users in the form of vehicle OTA to continuously improve user experience. This is very similar to smart phones, and it also gives Tesla the same characteristics and core advantages as Silicon Valley technology companies. Through mass production and price cuts, Tesla continues to attract more car owners into its self-built ecosystem. The large amount of data in the user’s use process helps Tesla deep learning and continuous improvement of products. It is updated and upgraded through vehicle OTA. Software and hardware, adding new ones, replenishing old ones, and constantly improving. end Although the performance of new energy vehicles in the policy and investment market is turbulent, the actual situation is that new energy vehicles have not yet reached the stage of rapid growth. In 2020, the global penetration rate of new energy vehicles is less than 5%, and the domestic penetration rate is 5.9%. There are many factors that hinder the high volume of new energy vehicles, such as battery safety, technological level, and completeness of supporting facilities such as charging, and another is price. In China’s 100,000-200,000-price range car market, the penetration rate of new energy vehicles is obviously not as good as other ranges, but this group accounts for 43.2% of the total. This part of consumers is more about the extreme price-performance ratio of the car, and the current electric car The cost of the power battery is still relatively high, so the price is significantly higher than that of fuel vehicles of the same level. On Tesla’s Battery Day in 2020, Musk announced to the audience that he would cut the cost of battery production in half, and plans to launch models priced at about US$25,000 (about 160,000 yuan) in the next three years. By then, it remains to be seen whether the catfish Tesla can wave its tail again and stir the market. references: books Ashley Vance “Iron Man of Silicon Valley: The Adventure Life of Elon Musk” Hamish Mackenzie “Tesla Biography: Realizing the Impossibility” Research report Guojin Securities “160,000 “Model 2″: Realization Path and Industrial Chain Impact” Guosen Securities “Discussing Tes Based on the Perspective of Business Model Reform” Tianfeng Securities “Tesla: From monthly data charges to SAAS-like business model, subverting the traditional auto industry” Industrial Securities “It is an electric car, but also a smart car.

]]> 26503 There will be no more tourist scenes like “broken bees” after Covid-19 https://en.spress.net/there-will-be-no-more-tourist-scenes-like-broken-bees-after-covid-19/ Mon, 21 Jun 2021 03:28:08 +0000 https://en.spress.net/there-will-be-no-more-tourist-scenes-like-broken-bees-after-covid-19/ Major changes in the tourism industry after the pandemic will take place in four areas: tourism demand, health and hygiene concerns, digitalization trends, and sustainability.
In 2019, the number of tourists going abroad reached 1.5 billion people. The tourism industry creates more than 330 million jobs and contributes 10% of global GDP, according to World Travel and Tourism Council (rough translation: World Tourism Council).

The explosion of mass tourism has allowed many people to visit new places without learning about the local culture or language. Many tourists only meet locals when cleaning hotel rooms. 16 months of closure because of the Covid-19 pandemic has caused the tourism industry to suffer. However, this huge industry that holds hundreds of millions of jobs is not going to collapse. It will return with the hope of changing in a sustainable direction, for the better, South China Morning Post identify. Karon Beach in Phuket (Thailand) is deserted on September 30, 2020. Photo: SCMP. Report of World Travel and Tourism Council in September 2020 identified four major changes in the future of tourism: travel demand, health and hygiene concerns, digitalization trends, and sustainability. In terms of demand, visitors will shift to prefer things that are familiar, predictable and reliable, which means local tourism is boosted. That will be evident in major countries with solid tourism foundations such as the US, European countries, Japan and China. International tourists will pay more attention to local characteristics instead of rushing to any place containing the combination of “blue sea, white sand, golden sunshine”. Airline packages will become obsolete. Health and hygiene concerns do not stop at temporary levels. Attending events, especially indoor and crowded ones, is challenging. The pandemic has made foreign travel dangerous, especially for developing countries with weak health infrastructures. The cumbersome administrative procedures to check visitors during the epidemic season will hinder this demand. The trend of digitalization in tourism will interfere and influence in two opposite directions. On the one hand, social networks will help plan trips without human contact and reduce dependence on travel agencies. On the other hand, the need for reliable sources of information can also strengthen the role of travel agencies. In addition, digitalization will also raise concerns about data privacy in international travel. Finally and most importantly, sustainability is effectively addressed. Mass tourism has caused great harm to the environment, “polluting” the experience and enjoyment of trips. The beaches of Bali (Indonesia) or Boracay (Philippines) are much less attractive when filled with plastic waste and untreated sewage. Crowding along the Great Wall at the Badaling section with thousands of other hikers or queuing to conquer Everest lowers the excitement of the experience. The Chinese crowd the Great Wall as fears of an epidemic fade. Photo: CNN. Business trips will be limited but more purposeful, as deep knowledge of foreign markets and different cultures remains key to the success of international businesses. This affects the airline industry, but it’s not bad news. In the future, the tourism industry will probably still hold 330 million jobs and serve 1.5 billion people a year or even more. However, visitors will pay more attention to the local environment and culture. Small groups of traveling friends will be formed to replace crowded groups like “broken bees”.

Recently, on Youtube Review Movie channel, the latest behind-the-scenes footage of the film has been uploaded The taste of friendship . In the clip, there are 3 actors Manh Truong, Phuong Oanh and Nam Anh who are practicing dialogue and also directed. Besides, the costume and hairdressing team are also busy preparing for the actors to show up in time.

Before each real scene, the actors will sit together to rehearse the dialogue first as well as discuss the script to add or cut the inappropriate parts. Like in this behind-the-scenes clip, the female lead Phuong Oanh suggested to the director to drop a line for a reasonable reason. According to the actors’ lines, it seems that at this stage Phuong Nam and Hoang Long began to love each other, the title was changed to “brother – me”. Phuong Oanh focused on learning the dialogue while Manh Truong seemed to be sick, he coughed a lot. Meanwhile, the costume party took advantage of stitching up the missing button of the male lead Hoang Long. Everything will be fine if our handsome male lead screams, making the whole crew startle thinking that he was stabbed by a needle. At this time, the only person who was sober because “catching cards” was Manh Truong was Phuong Oanh. Phuong Oanh humorously said: “Wow, that’s amazing. I saw a camera showing up. Whoa oh my. Poor girl, she’s out of her mind, isn’t she” . Phuong Oanh showed a lot of love for the costume staff because Manh Truong’s screams made her startled and scared. Is it possible that the female lead understands her co-star and does not hesitate to “unmask” Manh Truong? While Manh Truong and Phuong Oanh were practicing their dialogue, Nam Anh didn’t seem to know what to do next. Maybe it’s because she hasn’t reached the part where her appearance is yet. The actress only knows how to do cute things outside while watching people work. At the end of the clip, Manh Truong excited the audience with his sweet line when he told Phuong Oanh: “But you’re my lover” . Perhaps right now, the feelings of Hoang Long and Phuong Nam are very sweet and romantic. In addition, the female lead Phuong Oanh was very happy when she was praised for being pretty. Hopefully in the near future the audience will see more behind-the-scenes clips of the film The taste of friendship .

]]> 25004 Behind the scenes of Momo’s annual grand ceremony: the release of new value of “social + live broadcast” https://en.spress.net/behind-the-scenes-of-momos-annual-grand-ceremony-the-release-of-new-value-of-social-live-broadcast/ Wed, 16 Jun 2021 10:09:10 +0000 https://en.spress.net/behind-the-scenes-of-momos-annual-grand-ceremony-the-release-of-new-value-of-social-live-broadcast/

Technology from the media / Lao Hu Shuo Technology

On June 12, Shanghai Mercedes-Benz Cultural Center, Momo’s 2021 live broadcast annual grand ceremony was staged. Jackie Chan, Zhang Shaohan, Zhang Xinzhe, Hu Haiquan, VaVa, Gao Jin and other celebrities all attended the show. Li Xiang, Li Ai, and Da Zuo partnered to host and performed on the same stage with dozens of popular Momo anchors, bringing an audiovisual experience to online and offline users feast.

That night, Momo officially awarded the top ten male and female anchors of 2020, ten new institutions and other awards to the host. At the same time, the LED display of the Shanghai Global Harbor Twin Towers also showed a huge launch of the Momo Live Broadcasting Annual Festival, which created momentum for the MOMO Live Broadcasting Festival held at the Mercedes-Benz Cultural Center that evening.

This is already the fifth annual festival created by Momo in a row. After five years of sharpening a sword, behind Momo’s 2021 live broadcast festival is Momo’s new value of “social + live broadcast” in full bloom.

Echoing the annual ceremony, Momo once again handed over a beautiful report card. Just a few days before this live broadcast annual festival was held, Momo’s 2021 Q1 financial report released on June 8 showed that Momo’s net revenue in the first quarter was 3.470 billion yuan, exceeding Wall Street’s expectations; net profit was 633.7 million yuan. Profitable for 25 consecutive quarters.

It is worth noting that among the net revenue, Momo’s live broadcast service revenue reached 1.9621 billion yuan. Moreover, the Momo Master App has 115.3 million monthly active users, a record high. Among them, among the monthly active users, the total number of paid users of Momo’s live broadcast service and value-added service reached 12.6 million after deduplication.

The revenue capacity of live broadcast and the continuous growth of paying users for live broadcast demonstrates the powerful power of Momo’s “social + live broadcast” differentiated play. This is in the live broadcast industry where competition is fierce and profitable, Momo’s live broadcast business is very impressive. .

Also in this June, in addition to LED advertising screens, Shanghai People will also visit major bus shelters, subways, buses, office buildings, etc. in well-known landmark areas such as the Bund, People’s Square, Xujiahui, Nanjing Road, Lujiazui, and Shanghai Expo Valley. Saw the advertisement that Momo put on the host.

On one side is the brilliant live broadcast data, and on the other is the huge annual live broadcast festival. So far we have got a glimpse of the charm of Momo’s “social + live broadcast” model. The most important thing is that ahead, Momo in this mode has more room for imagination.

  1. The annual grand ceremony, a booster for the high-standard development of the live broadcast industry

    From the first held at the Water Cube in Beijing to this year’s Shanghai Mercedes-Benz Cultural Center, Momo’s annual live broadcast of the year has convened Li Yuchun, Li Bingbing, Mao Buyi, Xue Zhiqian, Lin Yilian, Deng Ziqi, Gigi Leung, and Jackie Chan. Stars such as, Zhang Shaohan and Momo’s popular anchors compete on the same stage, and they have sharpened their swords in five years. The annual Momo Live Broadcasting Festival has become synonymous with high-standard and influential activities in the current live broadcast industry.

    The significance of Momo Live’s annual festival is that by cultivating excellent anchors on weekdays, excellent anchors have a larger stage and fully release the dual influence of excellent anchors and Momo Live in the industry. In 2020, under the epidemic, Su Xiaosu, an all-round anchor, successfully made her debut on Momo. Her single “Watching the Sea” received extremely high reviews. The music champion Dong Shuangshuang is known as “Caiyun Girl”, and has representative works such as “Caiyun Girl”, “Happy Fish” and “Love to the End”.

    Behind the high popularity of the above-mentioned anchors both inside and outside the Momo platform, it is the blessing of Momo’s live broadcast industry status and influence. These popular anchors competed fiercely in the annual festival competition on the Momo platform, and finally competed on the same stage with the stars on the Momo live broadcast annual festival, and gained support from online and offline fans. This move will be of great benefit to both personal growth and the development of the Momo live broadcast platform.

    It can be said that the annual Momo Live Broadcasting Ceremony is not just a large-scale event, it is also a big stage for amateur stars and a booster for the high-standard development of the live broadcast industry. Through Momo live broadcast, more and more people’s lives have been changed.

  2. Behind the live broadcast revenue of 1.962.1 billion, create a “social + live broadcast” highland

    As we all know, Momo started with social interaction, which is its core and a powerful tool. In addition, Momo later acquired Tantan, and its social power was further strengthened. Through the differentiated play of social + live broadcast, the current live broadcast revenue of 1.962.1 billion yuan has been achieved, which is of great significance to Momo.

    Because the competition in the live broadcast industry has become fierce for everyone to see, it is even more difficult to stand out in the fierce market. How did Momo do it?

    Behind this is the advantage of Momo’s “social + live broadcast”.

    According to QuestMobile statistics, in July 2020, Momo ranked fourth on the TOP list of post-90s Internet mobile social users, second only to the three giants of WeChat, QQ and Weibo. In the China Mobile Internet 2020 Annual Report released by QuestMobile, Momo ranked first in the field of user-scale community dating on the Internet Strength Value List. It can be seen that Momo has built a sufficiently high social barrier and formed its own user scale and activeness advantage.

    When live streaming meets social networking, Momo fully releases and utilizes the advantages of the integration of social networking and live streaming.

    Momo CEO Wang Li once described Momo like this: “As a young social product, Momo has hundreds of millions of users interacting on it. The essence is that it gives young people spiritual comfort to a certain extent. The problem still needs to be solved by people. Only the interaction between people can polish the curve of life.”

    Specifically, Momo launched nearby live broadcasts and dating live broadcasts, becoming a major killer of live broadcast products. Momo has also developed a variety of “social + live broadcast” gameplay innovations, allowing users to gamify and interact while watching live broadcasts. Such efforts and explorations in product, operation, and interactive innovation have brought the life arc of live broadcast users, which not only achieves user growth, but also has breakthroughs in payment ratio and payment capabilities of Momo’s live broadcast platform compared with other live broadcast platforms. .

    Moreover, the strong social relationship established by Momo makes the entire user more binding and attractive than other live broadcast platforms. The live broadcast also realized the further activation of Momo Changwei’s paying users. In the end, the users of Momo Live showed excellent performance in stickiness, consumption ability, and willingness to pay.

    Relevant data has already confirmed this point. In 2019, the “Social + Live Broadcasting Development Research Report” released by QuestMobile Research Institute showed that Momo users accounted for 46% of high-end model users, and paid users accounted for 15%, second only to the integrated e-commerce platform Taobao, and nearly 20% of Momo users. The monthly online consumption level of Mo users is more than 1,000 yuan. You know, this is the data two years ago, and now Momo has gone further in the development of social + live broadcast.

    In other words, through the five-year Momo Live Broadcasting Festival, what we can see is that Momo, the leader in the live broadcast industry, has already created its own social + live broadcast highland, which is another single live broadcast platform. Unattainable.

  3. The new stage of the live broadcast industry, with greater imagination in the future

    If we look at the five-year journey of Momo Live’s annual festival from the perspective of “the strong are always strong, the Matthew effect”, we can also find that behind this high-standard live broadcast event that lasted for five years is the continuous moat of Momo Live. Deepening is also a manifestation of Momo’s greater influence as a head live broadcast platform, stronger user acquisition capabilities and lower content acquisition costs.

    Whether it’s Momo’s open social attributes combined with live broadcast innovative gameplay, or live broadcast of annual festivals and daily offline and online integration activities, Momo’s unique position in the live broadcast track makes its monetization ability increasingly stronger. In the past five years, live broadcasting has been the “cash cow” of Momo’s commercialization.

    Although Momo only entered the live broadcast in 2015, this latecomer has repeatedly used social networking to make continuous efforts. Momo Live has its own traffic portal and ecosystem. After all, for the live broadcast model, social interaction is naturally required, and undertaking the important task of live broadcast to pull new life also requires the sharing of social interaction to achieve the fission effect.

    In the author’s opinion, the social gene coincides with the needs of live broadcast netizens for social interaction, and socialized live broadcast has a future. Because only the fun live broadcast new gameplay that drives users through social interaction can further occupy user time and ensure user retention. With social power, huge user traffic and activity are guaranteed.

    Moreover, among all social platforms, Momo has the youngest users. The young will have the future world. With this advantage, not only can it continue to deepen Momo’s own moat in the live broadcast industry, but also open up more room for imagination of Momo social + live broadcast in the next few years.

    At present, in addition to optimizing the live broadcast ecology of Momo’s main station, Momo is also introducing live broadcast in Tantan. At the same time, both Momo’s member products and Tantan’s member products are in the process of exploration. This series of adjustments is conducive to the long-term development of Momo’s live broadcast ecosystem. In the future, Momo will continue to make efforts in anchor training and content optimization. At the same time, it will continue to make more attempts in public welfare and positive energy.

    In short, the domestic live broadcast industry has already passed the first half. Nowadays, the way for live streaming products to acquire users based on purchases has basically been blocked, and there are almost only two paths left for user acquisition: competition for stock users and recall of silent users. This is exactly the strength of Momo.

    From the perspective of the industry environment, the new crown epidemic has accelerated the maturity of the live broadcast industry, and more and more potential demands have been awakened. The live broadcast industry has truly entered a new stage-live broadcast continues to collide with thousands of industries to create new possibilities. Ahead, Momo’s live broadcast will also evolve and finally shine with new brilliance.

Mangoes in the South have fallen in the garden, and the North is expensive Mangoes in the South and North of our country are facing opposite fates. While mangoes in the South are full of orchards, mangoes in the North are expensive and high prices.

Similarly, zucchini grown in Vu Thu, Thai Binh has reached the harvest period but no traders have asked to buy it. People bring to the market to retail for 2,000-5,000 VND/kg. Last year, the price of pumpkin was 10,000 VND/kg. In Hanoi, the price of zucchini is 7,000-10,000 VND/kg. In addition to zucchini, pumpkin prices also dropped to only 5,000-6,000 VND/kg.

With the return flight from Ho Chi Minh City to Hanoi departing on June 2 and returning on June 5, the cheapest fare is currently at nearly 900,000 VND including taxes and fees. Compared to the last time it hit the bottom, domestic airfares inched slightly, partly because the preferential tickets for 0 dong were sold out, partly because airlines increased taxes and fees to supplement revenue during a difficult market period. towel. The original ticket price offered by airlines is only 5,000 VND, 6,000 VND, 49,000 VND or 99,000 VND. Peach ‘disguised’ Sapa specialty costs only 20,000 VND/kg According to Tien Phong newspaper, on many roads in Saigon, peaches labeled as Sapa peaches are sold widely. The peaches “disguised” are plump and shiny Sapa peaches with extremely cheap prices, only from 16,000-20,000 VND/kg. These large and juicy peaches are advertised by small traders as originating from Sapa. Mrs. C., a small trader selling fruit at Hoa Binh market (District 5, Ho Chi Minh City), affirmed: “Peach sold in carts, street vendors are “fake” peaches, and mine is the main Sapa. brand. Those who sell peaches for less than 20,000 VND are not from Sapa, and I don’t know where the origin is. Sapa peaches must be big and round, ripe like this to be real.” The price of live pork has dropped sharply, the price of meat in the market has not been reduced yet In recent years, live hog prices have continuously decreased. At the beginning of May, hog prices were at their lowest level in a year and are forecast to continue falling. Currently, the price of live pork is purchased in the range of 64,000-69,000 VND/kg. Compared to the same period in 2020, the price of live hog across the country has decreased from 30,000-32,000 VND/kg. But the price of pork sold at markets and supermarkets is still high.

In traditional markets, the price of pork is currently at 120,000-160,000 VND/kg. Compared to the same time last year, the price of pork decreased by 25,000-35,000 VND/kg. Explaining the record drop in live hog prices, but the selling prices are still high, Mr. Nguyen Van Trong, Deputy Director of the Department of Livestock Production (MARD) explained, the reason is from slaughter to sales in Vietnam. Nam is still going through many intermediate stages. Each stage costs additional costs, leading to the finished meat reaching consumers without enjoying the desired price. Green mangosteen guts ‘fly’ to Hanoi, the ‘chat’ price is still expensive At this time, mangosteen begins to be in season. Besides the ripe red, sweet, and succulent mangosteen fruits costing from 45,000-80,000 VND/kg, the mangosteen with the green skin, crispy intestine, and slightly sour taste is sought after by many people. Green mangosteen flesh costs half a million dong/kg (photo: NT) Mangosteen when green is still a rare specialty dish, because the collection and preliminary processing takes a lot of effort. Moreover, because there is only one season each year, the price of this fruit is not cheap. Unpeeled green mangosteen costs from 80,000-95,000 VND/kg. Particularly, peeled mangosteen is extremely expensive, up to 480,000-650,000 VND/kg depending on the time. Because, you have to peel about 4-5kg of fruit to get 1kg of intestine. Electricity is in short supply, prices increase Sharing on Nguoi Lao Dong Newspaper, Mr. Truong Hoang Thanh, in charge of trading a system of electronics supermarkets in Ho Chi Minh City, said that most new model electrical products have increased in price by at least 3-5%, especially television increased sharply by 10-20%. Meanwhile, a representative of Media electronics company announced that all items have increased in price from 8-20%. Similarly, Mr. Le Xuan Hoan, General Director of Kangaroo Group, cited the price increase of components by 20%, copper materials by 50% and plastic by 20%… to explain the price adjustment plan. products add 10%-20% in the coming time. Meanwhile, the expected price increase at Viettronics Joint Stock Company is 10-30%. Manufacturers warn that the TV supply shortage will continue from now until the end of the year due to the impact of the global chip crisis. The reason for the shortage of electrical and electronic goods, the price increase is due to the 3-4 times increase in the cost of transportation and the 8-9% increase in the component price compared to last year.

]]> 21419 ‘No project has been designed with lighting like Park Hyatt Phu Quoc’ https://en.spress.net/no-project-has-been-designed-with-lighting-like-park-hyatt-phu-quoc/ Tue, 01 Jun 2021 09:46:09 +0000 https://en.spress.net/no-project-has-been-designed-with-lighting-like-park-hyatt-phu-quoc/ According to Creative Director of ASA Lighting Design Studios, the lighting design at Park Hyatt Phu Quoc is perfect from concept, execution to technology and financial investment.

“In Vietnam, I have never seen a project with such a high level of investment in lighting as this project,” said Dr. Tran Van Thanh, co-founder and design director of ASA Lighting Design Studios. Having cooperated with many large resort corporations, he was still surprised by the scale of the project in this pearl island. – The design of the Park Hyatt Phu Quoc project bears the mark of Nathan Thompson – the founder of The Flaming Beacon. He participated in most of the meetings to discuss lighting design for the project. Not only that, he also brought to this project many lighting techniques and effects from the perspective of an expert. It must be added that he is one of the people with extensive experience in the field of stage lighting. Therefore, the idea of ​​lighting design for each area in the Park Hyatt Phu Quoc project is like arranging for each scene of a play. Here, the light not only needs to be beautifully designed, but also has to bring a “dramatic” feeling. The space is staged with many layers of metaphorical corridors to evoke a strong impression for visitors to stay. – As far as I know, this is the first project in Vietnam that applies dynamic lighting technology in the entire construction process. This technology is not only used in luxurious public areas, but also appears in each mansion. This is the first time in a resort where each bedroom is individually programmed with multiple lighting scenes, allowing to transform the atmosphere of each suite. The luxury of this project is also reflected in the fact that every area has a calibrated scenario, even the swimming pool and garden are programmed with many different lighting scenarios. Lighting solutions are designed to suit the time of day. If the morning light is gentle and elegant, the afternoon is romantic, then the evening brings a feeling of warmth and relaxation. These sensations are all adjusted through the brightness and tone of the light, from bright white to warm. The meticulous attention to detail is also reflected in the fact that we have a separate scenario for the sunset, which happens only 15 minutes. Designers had to calibrate at the scene, making sure the moment appeared just as the sun was about to set, and the transition matched when the last rays of sunlight disappeared. This process requires engineers to calculate the correct solar orbit whether it is the summer solstice, winter solstice, spring or autumn equinox. At the end of the romantic 15 minutes of sunset, the lighting is changed, setting the scene for the late afternoon when guests are about to leave the room for dinner, and will automatically activate to welcome the owner back to rest. . In addition, safety and comfort factors are also put on top. We have sensors all over the resort. Light sensor system, landscape lights will react to the weather environment to automatically activate when it’s raining, cloudy, low light… Thus, occupants will always feel safe and comfortable in every situation. time. These are just a few examples of the meticulous care in design that promises to bring an unforgettable experience to visitors at Park Hyatt Phu Quoc. – With such a unique design and technological requirements, the project had to use many custom-made decorative lights. These are unique lighting tools for the project, inspired by fisheries, fishing villages, moonlight… creating a poetic scene of Phu Quoc but also luxurious enough with the stature of Park Hyatt. I am especially interested in the design of the lights in the garden, they are accented with round spheres, giving off a very interesting amber light. The light of each sphere is filtered through a layer of ivory silk fabric, creating a magical golden color that cannot be reproduced with modern lights. This is also a bold experiment, combining modern design and traditional Vietnamese techniques. Besides, the lamps that project plants meticulously hidden in brown glazed crockery are also a very Vietnamese mark. Or a pair of seemingly simple night lights, but inside use LED chips with turnable white technology from 3,000K to super warm 2,200K colors, to almost accurately simulate the magical light of the candles only in the palace. old. – In order to have many lighting scenes for each space in the resort villa, tree, lake, etc., the control system must be invested with modern scale. That requirement also includes fine-tuning every detail, the lighting scene is smooth, the colors are synchronized, and the light quality is pure. So, behind those lighting experiences must be the equipment system invested, in this case, from BIM Land investor of BIM Group. Besides, the project also has the participation of The Flaming Beacon, a very famous name in the field of hotel and resort lighting design in the world. This company is based in Australia and has implemented many projects in 36 countries, which are highly appreciated by professionals and customers. In Vietnam, The Flaming Beacon is no stranger to being a partner of two high-end resorts, which can be said to be the names that set the standard of luxury resorts in Vietnam. The participation of The Flaming Beacon in the Park Hyatt Phu Quoc project is a proof that this will be the next luxury resort in Vietnam in the near future. Meanwhile, ASA Lighting Design Studios is a familiar name to investors, large and high-end customers in Vietnam. In more than 100 projects implemented, ASA has had projects of international stature such as Dragon Bridge (Da Nang), Nha Duc (Ho Chi Minh City). Park Hyatt Phu Quoc is the seventh project that ASA works with BIM Group. We are long-time partners, partners with many years of great cooperation to create quality projects. – The combination of two big-name companies in the industry will ensure the quality of the project’s lighting design. With ASA’s deep, strong expertise and understanding of Vietnamese culture and people, plus international quality design from The Flaming Beacon, I can confidently say that the Park Hyatt Phu Quoc lighting project will Perfect in both function and aesthetic quality.

]]> 19751 10 ungainly mistakes in the fight scenes between humans and animals in blockbusters https://en.spress.net/10-ungainly-mistakes-in-the-fight-scenes-between-humans-and-animals-in-blockbusters/ Sat, 29 May 2021 15:45:08 +0000 https://en.spress.net/10-ungainly-mistakes-in-the-fight-scenes-between-humans-and-animals-in-blockbusters/ The human-animal fight scenes in movies are often spectacular, but sometimes in order to create dramatic scenes, directors completely forget about some aspects of biology.
Here are some stunning scenes in blockbuster movies but can’t happen in real life.

The Revenant (2015) Movie content: The Revenant is based on a true story, the film tells the story of the hunter Hugh Glass (played by Leonardo Dicaprio). After a bloody battle with the Native Americans, Hugh was wounded and ruthlessly abandoned by his comrades in the snowy mountains. From there, Hugh Glass must do everything to survive the brutal cold, predators and war with the tribes in the wilderness. Thanks to his strong will, the hunter miraculously survived, crossing a distance of more than 3,000 miles (4,828 km) alone to return and take revenge on John Fitzgerald (played by Tom Hardy) – who was once the old friend of mine. The scene where Hugh Glass (Leonardo DiCaprio) is attacked by a mother bear is one of the most spectacular and unrealistic moments in this movie. The bear used its claws and fangs to bite and jump on Hugh. You may not know: The bite force of the gâú is 1,160psi (it’s like a human biting a sausage), their claws are 10-15 cm long and their weight is about 300-400 kg. You see, no one can survive such a war. Another strange point is that the grizzly bear attacks the main character because he is a threat to its cubs. For a mother, nothing is more important than protecting her cubs, but the bear just stops in the middle of a fight, leaving the opponent alive and gone. In another scene, Glass takes off his wet clothes and gets inside the horse’s belly to keep warm. It was a method used by many soldiers during the war, but…the main character spent the whole night inside the horse. Since the snow was everywhere, the temperature was definitely below zero and the horse’s corpse was dead. will freeze after a few hours. If it was in real life, Glass would have no chance of coming back alive the next morning. He could freeze to death in the night. In short, although “The Revenant” is based on a true story, we should only treat it as a feature film. The Leader – Alpha (2018) Movie content Alpha: The Leader is an ambitious action-adventure film from Sony. Not only possessing an overwhelming exterior depicting the majestic ancient world, the work also embraces an extremely touching scenario. The film is the story of the feud between a prehistoric boy (Kodi Smit-McPhee) and a stray wolf. Also from here, human history completely changed. In this movie we enjoy the majestic landscape and beautiful friendship between a boy and a wolf. But there are many mistakes in the movie that are quite obvious. The beginning of the film is the fight of a boy and a buffalo. But you can’t say it’s a war either: The animal just attacked the boy, and if it were in real life, he’d be broken/paralysed. At the end of the attack, the boy falls from a rock but only dislocates his hip. The wolf’s behavior is also quite strange. Its injuries don’t look too serious and a wild animal would rather follow its pack than stay with its enemies – a wolf can still walk on three legs. . Talk a little bit about the appearance of the wolves. We see prehistoric mammoths and saber-toothed tigers in the movies, but the wolves in the movie look like today’s wolves and are no bigger than a normal dog. How can they survive in a world full of giants? The Meg – The Meg (2018) Another recently released movie about a giant shark. It is difficult to judge the appearance and behavior of prehistoric monsters, but all creatures will be subject to certain biological laws. The size of the shark in the film is described as 70 – 75 ft (21.3 – 22.8 m) long. But scientists think its size was 60 ft (18 m). One of the heroic characters in the movie also said that such a shark could easily bite a whale in half. But they do not specify the size of the whale. What do we imagine when we think of whales? It is true that there are really huge whales. But there are whales that are only 13 – 16 ft (about 4 – 5 m) long like the dwarf sperm whale, while the size of a blue whale is 110 ft (33.5 m) – almost twice the size. shark size. As for bite force, sharks can bite a whale in half. But can the shark expand its jaws to that extent? Scientists have proven that megalodon can attack whales, but these whales must not be too large, only 40 – 50 ft (12 – 15 m) long. Sometimes in the movie, the shark attacks only one person (one of the main characters). But scientists don’t think this is characteristic of prehistoric predators. They will not chase 1 or 2 humans, but may swim to attack places with many people (such as the beach). In the beach scene at the end of the movie when the megalodon hunts on the beach, the shark approaches people swimming far from the shore and opens its mouth to swallow them, however it suddenly hears the sound of whales and swims away. . But in reality, it would have easily swallowed the prey that was lying right under its nose and continued to attack other victims.

]]> 18904 The times when the actress was mistreated when filming sensitive scenes https://en.spress.net/the-times-when-the-actress-was-mistreated-when-filming-sensitive-scenes/ Fri, 16 Apr 2021 13:33:07 +0000 https://en.spress.net/the-times-when-the-actress-was-mistreated-when-filming-sensitive-scenes/ Many Hollywood actresses expressed their dissatisfaction because of the lack of respect from the director when performing hot scenes on set.

Sarah Tither-Kaplan in The Long Home (2017): In 2018, Sarah Tither-Kaplan was one of five women who accused James Franco of inappropriate behavior or sexual exploitation of young actresses. According to Tither-Kaplan, Franco promises to give them a chance to advance in Hollywood. In return, the girls have to respond to the actor’s request even if they don’t want to. Image: Tumblr.

Sharing with The Times, Sarah Tither-Kaplan said that in The Long Home, she and her co-star were asked to make a scene sensitive to Franco. During filming, James Franco arbitrarily removed the protective sticker of the actress while continuing to caress. The other two actresses have also had negative experiences on set. They were scolded for not accepting the semi-lock in front of the camera. Photo: Rabbit Bandini Productions.

Jessica Alba in Machete (2010): In 2010, Jessica Alba surprised the audience when she was naked in a movie scene Machete directed by Robert Rodriguez. According to the The Daily Mail, when filming the scene, the actress is still wearing underwear. The suit was later removed using computer graphics technology, making it feel as if Alba was really naked on the screen. Jessica Alba always insists that she can dress revealing or pose sexy for the role, but will never appear on screen without a piece of cloth to cover her body. However, the movie scene Machete after being edited, it went against this principle. According to the CinemaBlend, director Rodriguez’s decision has violated Jessica Alba’s basic moral rights.

Gina Ravera in Showgirls (1995): In the movie, Molly’s character, played by Gina Ravera, was forcibly beaten by Andrew Carver (William Shockley). Ravera said she is serious about filming the scene. However, the lack of detailed explanation by director Paul Verhoeven, as well as the lack of technical and psychological support before filming, Ravera suffered both physical and mental injuries. Image: MovieStillsDB.

On the set, because we wanted everything to be true, Verhoeven and the actors were too strong, causing Ravera to dislocate. After Showgirls, the actress always turned down roles that asked her to transform into a victim of sexual violence. Ravera didn’t want her career to be framed in a forced scene.

Sharon Stone in Basic Instinct (1992): In the memoir The Beauty of Living TwiceActress Sharon Stone recounted her shock when she saw the classic leg shift for the first time in Basic Instinct on the big screen: “It was the first time I saw my sensitive parts show on the screen. Before filming the scene, I was reassured that ‘The audience won’t see anything. I need you to take off my underwear, because its color is revealed in the frame. ” Sharon Stone gave director Paul Verhoeven a slap. Image: GQ.

Even so, the actress still could not stop the scene from being shown on the big screen. “I’m just an actress, a woman, what do I have the right to choose? But I have options. So after thinking a lot, I accepted to let the scene appear on the screen. Why? Because it is true to the movie as well as character. And after all, I’m the one doing it, ”she concluded.

Maria Schneider in The Last Tango in Paris (1972): After nearly half a century, The Last Tango in Paris remains a prime example of how filmmakers are not being used to treat actresses on set. In the movie, the middle-aged man character played by Marlon Brando has a violent flesh relationship with a strange girl played by Maria Schneider. Image: United Artists.

In 2013, director Bernardo Bertolucci admitted that he and actor Marlon Brando had planned a rape scene without prior notice to Maria Schneider – then 19 years old – in order to capture her honest responses. The rape on the set of The Last Tango in Paris left serious psychological trauma to Maria Schneide. Since then, she turned down every role that required her to be nude on the screen.

Some sources have said that director Joss Whedon has made many threats to actress Gal Gadot (playing Wonder Woman) during the filming of Justice League. This information made many Vietnamese audiences angry, because Gal Gadot is currently one of the most beloved actresses in Hollywood.

The audience could not help but feel frustrated when they heard that the director locked Gal Gadot in a secret room because she refused to film sensitive scenes.

Specifically, when director Zack Snyder left the Justice League project in 2017, director Joss Whedon was led by Warner Bros. invite and supervise filming. Since then, Joss Whedon requested to return 75% of the film, “cutting” the original script quite deeply. At that time, Warner Bros. wanted to change the direction of the DC universe in the bright, humorous style of Marvel. Joss Whedon is also the director of the blockbuster Avengers every day, so the leader of this company entrusted the project Justice League. However, when it was released in theaters in 2017, Justice League was hated by professionals and fans because it was too bad, many “sexualized” segments of Wonder Woman.

During the campaign to release the movie Zack Snyder’s Justice League, actor Ray Fisher (playing Cyborg) has repeatedly voiced the actions “disgusting, bullying, unprofessional, unacceptable. “okay” by Joss Whedon on set. Both Gal Gadot and actor Jason Momoa (playing Aquaman) have voiced support for Ray Fisher. Warner Bros. The announcement has held a special investigation related to the incident, but did not publish the results of the investigation.

Recently, the news site The Hollywood Reporter revealed many controversial developments on the set of Justice League, especially regarding actress Gal Gadot.

The female star was not satisfied with the new direction the film exploited her Wonder Woman character, as well as the lines she had to say. Because of that, Joss Whedon is said to have threatened Gal Gadot’s career if she did not obey. Even he threatened to “lower the honor” of Patty Jenkins – director of blockbuster Wonder Woman series, who is also close to Gal Gadot.

A witness at the studio revealed that Joss Whedon also bragged to everyone about his intimidation of Gal Gadot, admitting that he deliberately forced the actress to say lines that she would certainly not like. “He told Gal Gadot that he was the writer, she would have to ‘shut up’ and read the lines, and then he could make Gal Gadot extremely stupid in this movie.”

This controversial scene is believed to be the intentions of Joss Whedon

Previously, it was reported that Joss Whedon locked Gal Gadot in a waiting room because she refused to film Flash falling on Wonder Woman’s chest. That shot was still shot by Joss Whedon with a stuntman, and even appeared in the official Justice League theatrical release.

Three months after Justice League hit theaters, director Joss Whedon withdrew from DC’s Batgirl project in development. When asked to respond to the charges on the Justice League studio, he declined to comment.

Before this new information, many viewers expressed anger and anger because Gal Gadot was unfairly treated and humiliated: “Inviting rival film director to make filmmaking, an unexpected move of Warner Bros”, “Joss Whedon is so heavy.”, “It feels like this Joss Whedon has a grudge against DC. No one can make such a bad movie “,” There is one more reason to hate this man. Dare my sister Gal Gadot! ”…

]]> 2429 Drone “behind the scenes player” https://en.spress.net/drone-behind-the-scenes-player/ Thu, 15 Apr 2021 18:04:07 +0000 https://en.spress.net/drone-behind-the-scenes-player/ Opening words: New occupations, new workers, born out of yearning, but also born out of “net”. Occupations that were originally born out of needs have become indispensable new occupations thanks to the catalysis of the Internet. Under the Internet craze, professional connotations have been reinterpreted, and professional characteristics and types are even more varied. In each era, there are always specific professional groups who are the witnesses and creators of life and business. To this end, we will use text, video and pictures to record career changes in the context of the times.


In the future, your express delivery is likely to fall from the sky, and they will ride drones over mountains and seas. In the day-to-day maintenance, overhaul and upgrade by Su Hao, a UAV assembly and repair engineer, these sophisticated and flexible aircraft are showing their amazing potential, breaking through the limitations of ground transportation, and challenging the time limit of express logistics. UAV installation and maintenance workers not only let the UAV take off, but also make it land accurately and safely. Tens of thousands of debugging times are only for express delivery to “fall from the sky” quickly and stably. With the breaking of technical cost and other bottlenecks, the era of drone delivery may be approaching.

Thousands of crazy trials to adjust and test flight at an altitude of 3,500 meters

Within 15-20 minutes, Su Hao and his team will send Matsutake mushrooms that grow on a high mountain at an altitude of 3,500 meters down the mountain. As soon as the news came out, this village in the western plateau of China exploded. After all, it has always been a tradition of villagers to climb rugged mountain roads and pick and transport matsutake by humans. It can condense hours or even a day’s work to 20 minutes, and almost no one believes that Su Hao and his team can do it.

In the eyes of people’s surprise, Su Hao is still full of confidence because he also has a group of “colleagues” named Fang Zhou. The Ark is an unmanned aerial vehicle with eight rotors that can perform flexible turns, ascent and descend, and stay in the air under the automatic control of the system. It can fly for 22 minutes with a load of 10 kg.

In fact, products like Matsutake are quite “squeaky.” You have to take it off as soon as it is fresh, otherwise once the umbrella is “opened”, the nutritional value and economic value will be quickly lost. Relying on the characteristics of drones such as flexibility, efficiency, and ability to complete instructions autonomously, Su Hao hopes to change the inefficiency of hand-carried shoulder transportation and free the villagers from time-consuming and labor-intensive transportation.

Of course, letting Matsutake “fly” down from a 3500-meter high mountain is also a scene exercise and application of SF Express in the production of fresh transportation by drone farmers. If successful, these accumulated experience will help more agricultural products go out of the mountains and increase the income of local residents.

All beginnings are hard. Compared with plains, the environment in plateau and mountainous areas is more complicated. The weather changes drastically. Rain or wind will affect the smooth operation of the machine. In addition, the steep and rugged terrain also increases the difficulty of base station construction. The drone seems to be a point-to-point flight, and behind it is a whole set of systems to support it, including weather monitoring systems, communication networking systems, etc. Su Hao and his colleagues must cooperate closely, not only to make the drone reach the destination smoothly and accurately, but also to ensure foolproof safety during the flight.

Not only must the matsutake “fly” down the mountain, but it must also land on the ground accurately and safely according to the set flight route.

For this reason, within 3 months, the team made countless adjustments and test flights, and gradually outlined the outline of the use of drones in the plateau scene, which was regarded as a whimsical concept turned into reality. This also made Su Hao deeply aware for the first time that technology can change logistics, and logistics can truly change people’s lives.

Playing with “toys”, the team of famous drones is growing

However, if you turn the time back to 2013, the drone industry will be both mysterious and unfamiliar in people’s eyes. After graduating from university, it is difficult for Su Hao to find drone-related positions in job recruitment. He was obsessed with interest during his studies and did not find the right soil for the first time. This niche field is only confined to enthusiasts. In various exchange groups.

Strictly speaking, the aerial photography of activities that people see daily, or the so-called “drone” in the fleet performance, actually tends to be more toward the concept of aviation model, and the “drone” that Su Hao specialized in at that time also belongs to In the field of model aircraft. This type of aircraft mainly relies on human control to complete performance or competitive content, and is not a drone in the strict sense.

According to the definition of the Civil Aviation Administration, a drone is an aircraft managed by a control station (including remote control or autonomous flight), also known as a remotely piloted aircraft. The ability to carry sensing, measurement and data transmission equipment and automatically perform remote tasks according to procedures has become an important feature that distinguishes UAVs from aviation models.

After graduating from university, Su Hao worked at a gas station. Although he was far from the dream of flying, after get off work, Su Hao would still spend a few hours repairing the aircraft model, and sometimes asked the “great god” in the circle about assembly problems. . “Some colleagues know that I play aeromodelling, but many people think it is a’toy’.” He said with a smile.

Unconsciously, the outside world and Su Hao’s life trajectory have quietly changed because of this “toy”.

In 2013, when Su Hao graduated, the Civil Aviation Administration successively promulgated and revised the “Regulations on the Management of Civil UAV Pilots”, “Regulations on the Operation of Light and Small UAVs (Trial)”, “Measures for the Air Traffic Management of Civil UAV Pilot Aircraft Systems”, etc. Regulations that civilian drones are more regulated at the regulatory level, which has also accelerated the use of drones in more scenarios.

By April 2014, the management of drone pilot qualification and training quality began to be taken care of by the China AOPA (Chinese Aircraft Owners and Pilots Association) under the Civil Aviation Administration, which means that drone enthusiasts will achieve “regularity”. Can pass the formal examination to become a professional drone industry practitioner.

In November 2016, Su Hao’s life trajectory ushered in a change. Based on his many years of love for drones, he almost easily obtained his own civil unmanned aircraft system pilot certificate, and finally had the opportunity to step into the industry he dreamed of. Like Su Hao, more and more job seekers are starting to flood into the drone field. In May 2017, the number of drone pilots with certification exceeded 14,000.

In February 2020, “UAV Installation, Adjustment and Maintenance Worker” officially became a new occupation and was included in the National Occupation Classification Dictionary. New occupations such as drone installation and maintenance workers and drone pilots have emerged due to the booming demand. The industry is entering a period of rapid development: According to the statistics of the Civil Aviation Administration, the number of registered drones in the industry has reached 523,600, and the annual flight volume has reached 1.594 million.

Break through spatial and geographical restrictions and build a bridge for online shopping in the mountains

After obtaining the qualification certificate, Su Hao became an unmanned aerial vehicle assembly and maintenance worker in SF Express in 2018. He summed up his career with “huge jumps”. “Before playing model airplanes was “happy flight”, but when it comes to the level of logistics operations, the requirements for the safety and stability of drones are very strict.” Daily maintenance, troubleshooting, software and hardware upgrades, Su Hao and the team There can be no mistakes. Behind every flight is a heavy responsibility.

It can be said that “black technology” such as drones really flew into people’s field of vision during the severe epidemic in 2020. In Wuhan, Shiyan, Ganzhou, Wenzhou, and Harbin, SF UAVs have built channels for transportation of materials. In the 32-day operation, drones flew more than 5,000 sorties, with a flight mileage of more than 22,000 kilometers, and more than 20 tons of materials were delivered to people.

In remote mountainous areas or scattered islands, the air superiority of drones not only eases the problem of unsalable agricultural products caused by inconvenient logistics, but also builds a bridge for residents’ online shopping. At present, Zhongtong is developing a hybrid UAV with a larger load capacity, which is expected to carry a load of 10-15 kg and a battery life of 100 minutes.

Transportation is inconvenient and labor costs are high. For these problems that plague the last mile of rural express delivery, drone delivery may become the optimal solution. In Tonglu, Zhejiang, Yunda’s 5G drone took off from an outlet in Fenshui Town, across the mountains and mountains, and delivered a Tonglu specialty Xueshuiyun green tea to customers in Zhangjiawu Village in just 16 minutes.

After several iterations, these “children” in Su Hao’s eyes have gradually grown into “reserves” of conventional capacity, expanding their potential in intra-city and inter-city high-efficiency transportation such as intra-city express delivery and inter-city express delivery. The vigorous growth of the drone industry not only enriches the competitive dimensions of enterprises in logistics and transportation such as trunk lines and branch lines, but also provides convenient and fast express services for consumers in more remote areas.

The transportation of matsutake on the plateau is just a microcosm of the drone flying in thousands of scenes, but it is deeply engraved in Su Hao’s mind. These smart and sensitive machines are breaking down barriers and filling the space-time distances between mountains and cities, inland and islands. People’s lives become different from this. More importantly, more people are understanding and approving the efforts of drone practitioners. “The hard work is worth it,” Su Hao said.

Therefore, in the field of logistics and express delivery, deep into the last kilometer or even 100 meters of the end of the consumer end, drones with wings that can fly freely set off again and again, echoing the express vehicles galloping on the ground.
